Vacuum dissolver for high-viscosity products
Elevate your production with precision mixing and deaeration, ideal for tackling high-viscosity challenges. This solution integrates seamlessly into your production line, optimizing batch processing while ensuring consistent product quality through advanced vacuum technology.
Processes and Deaerates High-Viscosity Liquids
The VKDV series by NIEMANN is a high-performance vacuum dissolver designed for the rigorous processing of high-viscosity materials. Utilizing modern frequency converter technology and a state-of-the-art mechanical pulley-drive system, it excels in effectively mixing, dispersing, and deaerating products like adhesives, pigment pastes, and coatings. Capable of processing viscosities up to 1,000,000 mPas, this equipment is essential for achieving uniform consistency and optimal product quality.
The floor-installed vacuum design accommodates batch sizes from 100 to 5000 liters, with driving powers ranging from 6.8 to 160 kW, ensuring versatility across multiple scales of operation. Integration into production lines is seamless with features like adjustable toothed discs under vacuum and customizable batch controls via KD-BATCH-CONTROL® systems. The equipment’s construction options include mild and stainless steel, with ATEX compliance for safe operation in explosive environments.
NIEMANN’s VKDV offers enhanced efficiency with features like double suction discs and container wall scrapers, significantly improving product handling. Ideal for industries ranging from paints and coatings to cosmetics and adhesives, it meets stringent quality standards and supports semi and fully automatic operation modes. The equipment is built to reduce energy consumption during high-speed operation while maintaining precise temperature control for material consistency.
